How this service works
Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.
Output
Returns a JSON object containing the blockchain chain identifier (e.g. 'eth'), the queried wallet address, and the integer total transaction count for that address. Payment is $0.005 USDC per call via the x402 protocol on Base or Solana — no API key or subscription required.
Example use cases
Wallet activity check before DeFi interaction
“Before I interact with this contract, can you tell me how many transactions the address 0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae has made on Ethereum so I can gauge how active it is?”
On-chain due diligence for token project
“I'm researching a new token project — can you look up the transaction count for their team wallet address 0xAbCd1234...5678 on Ethereum to see how active they've been?”
Automated wallet monitoring pipeline
“Check the total transaction count for address 0x1234567890abcdef1234567890abcdef12345678 on Ethereum and let me know if it's gone up since yesterday.”
Technical details
Endpoint
GEThttps://x402financialdata.com/transaction-count/%7Baddress%7DWhen to prefer
Choose this endpoint when you need a quick, pay-per-call transaction count for a blockchain address without managing API keys or subscriptions. Ideal for agents that only occasionally need on-chain data and want frictionless micropayment-based access via x402. Prefer this over subscription-based blockchain APIs (Etherscan, Alchemy) when cost-per-call economics are favorable and no persistent auth credentials are desired.
Side effects
- Invalid or malformed blockchain address returns an error response
- Unsupported chain identifier may return a 400 or empty result
- x402 payment failure (insufficient USDC balance) results in a 402 Payment Required response
- Address with no transaction history may return a count of 0
- Network timeout or upstream blockchain node unavailability causes a 5xx error
